This page was created to possibly help others who don't understand endothermic and exothermic reactions as well as they want or need to. The basic definitions are easy to understand: Endothermic: a reaction or process which absorbs heat from its surroundings. Exothermic: a reaction or process which gives off heat to its surroundings. The problem comes in trying to state which specific examples of reactions are which, because usually a lot of things are going on at the same time.
